Description
Technical field
The present invention relates to the gate used in hydraulic engineering, the self-locking pull rod of lifting gate is especially for.
Background technology
Rolling open and close machine lifting gate is coordinated to be common method in hydraulic engineering using pull rod, pull rod is opened and closed as elevator
Effective supplement of machine lift, greatly reduces the impulse stroke of rolling open and close machine, reduces the size and weight of rolling open and close machine, section
Equipment investment is saved.At present, when coordinating rolling open and close machine lifting gate with pull rod, pull rod device is in rolling open and close machine suspending head and lock
Between gantry crane ear, each component is connected using axis pin, and pull rod chain one end of more piece pull rod composition is connected with rolling open and close machine suspending head, and one
End is connected on gate lifting eye, and connection, the dismounting of pull rod are completed on inspection platform by manual operation.It is above-mentioned to be matched somebody with somebody using pull rod
Close rolling open and close machine lifting gate and be only applicable to gate vertical lift operating mode, under such conditions, rolling open and close machine suspending head, gate
Lifting lug and pull rod chain are perpendicular to the ground, and pull rod is long thin rod shape, assemble and disassemble and draw between rolling open and close machine suspending head and gate lifting eye
During bar, only pull rod is placed vertically just easy to the docking in lifting lug hole each other with wearing axis.The drawing of large capacity rolling open and close machine
Bar is heavier, in connecting rod, pull rod is hung in inspection platform vertically usually using interim lifting appliance, to ensure pull rod
Vertical state, the suspender of interim lifting appliance cannot depart from pull rod all the time, and axis connection is worn in pull rod and rolling open and close machine suspending head
When, rolling open and close machine suspending head and the suspender of interim lifting appliance will interfere, and cause rolling open and close machine suspending head can not be with drawing
Bar smoothly connects.In addition, when if interim lifting appliance is in working face with rolling open and close machine, the two cannot carry out work at the same time
Make, if carried out the work at the same time, can also interfere with each other.Only when pull rod is called in inspection platform by interim lifting appliance and is moved
After walking, rolling open and close machine just has the space of operation.To ensure that pull rod can smoothly wear axis connection, when interim lifting appliance is removed
Afterwards, the vertical state of pull rod how is kept, is problem to be solved.
The content of the invention
Present invention aims at provide a kind of self-locking pull rod for being used to lift by crane gate.
To achieve the above object, the present invention takes following technical proposals：
The self-locking pull rod of the present invention for being used to lift by crane gate, including the body of rod, are connected in the upper of the body of rod upper and lower end
Lifting lug and lower lifting lug, the upper and lower lifting lug are double shackle structure；The lifting hole(eyelet) of the upper lifting lug is the length longitudinally opened up along the body of rod
Pore structure, is provided with locking shoulder on the body of rod below upper lifting lug, and the locking shoulder is fixed on the body of rod by upper and lower interval
Upper support platform and lower support platform are formed, and the upper and lower support platform is axial to body of rod both sides along the lifting hole(eyelet) of upper lifting lug respectively
It is extended.
The cross section of the body of rod is i-beam structure, and the bottom of the body of rod is box-structure.
The invention has the advantages that the pull rod utilizes the locking latch function of itself, being not required to can be all the time by external strength
Vertical state is kept, facilitate pull rod wears pin connection, is particularly suitable for pull rod and coordinates large-tonnage travelling hoist to play port-cullis
The occasion of door.

Embodiment
As shown in Figs 1-4, the self-locking pull rod of the present invention for being used to lift by crane gate, including the body of rod 1, the body of rod 1
Cross section is i-beam structure（As shown in Figure 3）, the bottom of the body of rod 1 is box-structure（As shown in Figure 4）；It is upper and lower in the body of rod 1
Lifting lug 2 and lower lifting lug 3 has been respectively fixedly connected in end, and the upper and lower lifting lug 2,3 is double shackle structure；To make pull rod after sleeve
The axis connection of wearing of lifting lug can be carried out, the lifting hole(eyelet) 4 of upper lifting lug 2 is the long pore structure longitudinally opened up along the body of rod 1, positioned at upper lifting lug 2
Locking shoulder is provided with the body of rod 1 of lower section, the locking shoulder is by the upper and lower upper support platform 5 being fixed on the body of rod 1 that is spaced with
Support platform 6 is formed, and the upper and lower support platform 5,6 is set along axial extend to 1 both sides of the body of rod of lifting hole(eyelet) 4 of upper lifting lug 2 respectively
Put.Upper support platform 5 is used to support another section pull rod being connected with upper lifting lug 2, keeps pull rod to be in vertical state；Lower support
Platform 6 is used for the pull rod chain that pull rod or more piece pull rod form and is locked with gate on inspection platform.The present invention is in use, any one
Save the upper lifting lug 2 of pull rod can vertically sleeve under another pull rod being attached thereto in lifting lug 3.
When headstock gear is using present invention lifting gate, pull rod attended operation order is as follows（By taking gate declines as an example）：
The first step：Pull rod 7 waiting is sling vertically with interim lifting appliance, by 3 sleeve of lower lifting lug of pull rod 7 waiting
Connect on the upper lifting lug 2 of pull rod 8（As shown in Figure 5）, interim lifting appliance is removed, and keep pull rod 7 waiting to be worn vertically upward
Axis connection operates；
Second step：Headstock gear suspending head 9 is fallen, and pin connection is worn after being aligned with lifting lug 2 on pull rod 7 waiting（As shown in Figure 6）, this
The connection of pull rod 7 waiting is carved to complete.
3rd step：Headstock gear 10 does enhancing action and releases the locking of gate 11, then by pull rod 7 waiting, connect pull rod 8
And gate 11 is together sling and is transferred along gate slot, after transferring certain distance, by pull rod 7 waiting lock the lower support platform 6 of shoulder with
Locking beam 12 is locked on inspection platform 13 jointly, is disconnected the connection between headstock gear suspending head 9 and pull rod chain, is then carried out down again
The access of one section pull rod, the connection of next section pull rod repeat the first two steps（As shown in Figure 7）.
